Rivian Update: Charging Power of Rivian R1T/R1S Exceeds 210 kW

Additionally, the EPA's document details the vehicle's weight and confirms the absence of a heat pump.

Key Highlights

The EPA's certification document, which is listed on the rivianforums.com forum, contains new information regarding the Rivian R1T and Rivian R1S automobiles.
According to the report, the vehicles are equipped with an 11.5 kW onboard charger and a 210 kW DC fast charging peak, which is consistent with the manufacturer's earlier estimates.
The Rivian's battery has a capacity of 135 kWh and is comprised of nine modules containing 7,776 2170-type cylindrical cells.
The useable battery capacity may be 5-7.5 percent lower, as we saw certain "discharge energy" figures between 125 and 128 kWh, but this must be confirmed in a complete range test.

The EPA's certification document, which is listed on the rivianforums.com forum, contains new information regarding the Rivian R1T and Rivian R1S automobiles.

We extracted a few data from the public paper that appear to be significant.

Charging Power

According to the report, the vehicles are equipped with an 11.5 kW onboard charger and a 210 kW DC fast charging peak, which is consistent with the manufacturer's earlier estimates.

In March, the company stated that the R1T and R1S will charge at a rate greater than 200 kW and that future models will charge at a rate greater than 300 kW.

Both figures are peak values, however despite the fact that they are not the highest (particularly given the 135 kWh battery capacity), a peak value does not allow us to draw broad generalisations, as the average value may still be rather high.

Heat Pump

Rivian electric vehicles do not have a heat pump:

"08.06.01 Heat Pump Electric

N/A"

Weight

What's intriguing is some information regarding the weight. The R1T weighs 6,949 lbs at the curb, while the R1S weighs 6,916 lbs

Battery

The Rivian's battery has a capacity of 135 kWh and is comprised of nine modules containing 7,776 2170-type cylindrical cells. The nominal capacity is 360 Ah, and the operating voltage ranges from 216 to 459 V.

The useable battery capacity may be 5-7.5 percent lower, as we saw certain "discharge energy" figures between 125 and 128 kWh, but this must be confirmed in a complete range test.

On the other side, the "Recharge Event Energy" indicates 146-153 kWh, depending on the car and test.
